[classlib][beans] no IntrospectionException for PropertyDescriptor("a", Class.class)
------------------------------------------------------------------------------------

                 Key: HARMONY-1435
                 URL: http://issues.apache.org/jira/browse/HARMONY-1435
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Vladimir Ivanov


The spec says for java.beans.PropertyDescriptor(String propertyName, Class<?> beanClass):
"Constructs a PropertyDescriptor for a property that follows the standard Java convention
by having getFoo and setFoo accessor methods". The RI checks convention while Harmony not.

====================== test.java ====================
import java.beans.PropertyDescriptor;

public class test {
    public static void main(String[] args) throws Exception {
        System.out.println("res = " + new PropertyDescriptor("a", Class.class));
    }
}
=================================================
